Course Objectives:
The course is designed for engineers who are involved in the formation evaluation process, in which coring, mud logging productivity testing and wire line logging are the main components – well logs provide a comprehensive snapshoot of all the formation penetrated by a borehole. The course stresses the theory, measurements, applications and limitation of the available logging tools. Interpretation methods for rock type, litho logy, porosity and hydrocarbon saturation are reviewed.
